Dietary incorporation of sun dried cage layer maunre on performance of broiler chicknens

The performance, humoral immune response and carcass traits were evaluated in broiler chickens fed diet incorporated with sun dried cage layer manure. Day-old commercial broiler chicks (150) were distributed equally into 5 groups with 6 replicates of 5 chicks each. The birds were reared on raised wire floor battery brooders under optimum managemental conditions. A basal diet based on maize-soybean meal-deoiled rice bran was formulated. Subsequently, another 4 test diets were formulated by incorporating sun dried cage layer manure (SDCLM) at 2.5, 5.0, 7.5 and 10.0% level. All the diets were made isocaloric and isonitrogenous and fed ad lib. to 6 replicates of 5 chicks throughout the experimental period of 6 weeks. The body weight gain and feed conversion ratio of broiler chickens fed 2.5% SDCLM incorporated diet was comparable with that of control group. However, incorporation of SDCLM beyond 2.5 and 5.0% level in the diet resulted in significantly lower weight gain and poor feed conversion ratio, respectively. Dietary incorporation of SDCLM up to 5 and 10% level did not influence the dry matter digestibility or retention of nitrogen, calcium and phosphorus, and humoral immune response, respectively. Similarly SDCLM up to 10% in the diet of broiler chickens did not influence serum concentrations of albumin, globulin, phosphorus and activities of enzymes like SGOT and SGPT. However, the concentrations of serum protein decreased and that of uric acid increased by incorporation of SDCLM at 7.5% in the diet. Dietary incorporation of SDCLM up to 10% level in the diet of broiler chicken did not influence carcass traits such as dressing yield, gizzard, giblet or abdominal fat. However, the liver weight increased significantly by incorporation of SDCLM beyond 5% in the diet. It may be concluded that sun dried cage layer manure could be incorporated at 2.5% level in the diet of broiler chicken without affecting performance during 0 to 6 weeks of age.
